Gaming Things We Think Are Cool!! - Games that have 'special appearances' from other game characters.

That's what this page is about.

Rules for inclusion on this page:
#1 - Only cases where the guest character is either a playable character, or an enemy, boss or interactable opponent, count. No straight-up cameos, such as background appearances, costumes, as shopkeepers, quest-givers, etc..
#2 - They must be from separate series- Ryo Sakazaki in Fatal Fury Special counts, for instance, but Hibachi in DoDonPachi Resurrection doesn't.
However, it's OK if they're in the same story continuity but originate from different series (like Street Fighter and Final Fight).
#3 - Games that are crossover games to begin with (Fighters Megamix, Super Smash Bros, etc.) don't count, unless the crossover game is between one particular company or series and other companies / series are represented, such as guests in Smash Bros., Cole in Street Fighter x Tekken, and so on.
#4 - NO MOBILE GAMES. No exceptions.
#5 - Ultimately... I make the final say on whether it ends up on this page or not. Please understand.

Rules for page presentation::
#1 - English titles first, Japanese titles second.
#2 - Presented in chronological order, except when dealing with a series (i.e. Oneechabara / Aero Fighters)
We'll run through all remaining titles in that series, then go back to year order.
#3 - We'll only be listing initial / relevant release platforms and years, for space concerns.
#4 - We've divided things into 1980-1994 (this page), 1995-1996, 1997-1999, 2000-2009 and 2010-Present.

GORF
(Arcade, 1980, Midway)


Space Invaders & Galaxians
from, uh, from Space Invaders (Space Invaders) - Arcade, 1978, Taito
& Galaxian (Galaxians) - Arcade, 1979, Namco

How to Encounter / Notes:
The first scene of the game, Astro Battles, has the player fighting the Crab, Squid and Octopus Invaders, alongside the UFO.
The third scene of the game. Galaxians, has the player fighting the full Galaxian squadron, alongside the Boss Galaxian.
Most home ports of the game, such as the Atari 2600 version, redesign the Space Invaders and remove the Galaxians scene entirely.
Midway were the distributors of both Space Invaders and Galaxian in the US so this is, technically, a licensed appearance. Wonder if Taito and Namco knew about it at the time...



Galaga
(Arcade, 1981, Namco)


Spy Ship
from Bosconian - Arcade, 1981, Namco

How to Encounter / Notes:

How to Encounter / Notes:
Maitas first appear in Round 6.
Monstas first appear in Round 10.

Rainbow Islands: The Story of Bubble Bobble 2
(Arcade, 1986, Taito)

How to Encounter / Notes:
All of these enemies appear in the fifth Island of the game, Doh Island. [Name Source]
Doh serves as the island's boss.
The Round Start jingle is based on the Round Start jingle from Arkanoid, and while the music is replaced with silence, every time you jump it makes sound effects from Arkanoid to simulate the ball bouncing around.


Pig Soldier, Mage, Priest, Ghoul, Golem, Worm & Time-Up Devil
from The Fairyland Story - Arcade, 1985, Taito

How to Encounter / Notes:
All of these enemies appear in the first Secret Island of the game, Magical Island, unlocked by collecting all the Big Diamonds from Islands 1 to 7.

The Round Start jingle is based on the Round Start jingle from The Fairyland Story, and the music is based on the theme from the first 50 rounds of The Fairyland Story.


Darius Enemies & Electric Fan
from Darius - Arcade, 1987, Taito

How to Encounter / Notes:
All of these enemies appear in the second Secret Island of the game, Darius Island, unlocked by collecting all the Big Diamonds from Islands 1 to 7.
Electric Fan serves as the island's boss.
The Round Start jingle is based on the credit jingle from Darius, the music for the normal stages is based on the song Cosmic Air-Way from Darius, and the Round Clear theme is based on the Zone Clear song from Darius. The boss theme does not seem to come from Darius though, can you help?

How to Encounter / Notes:
NES / Master System / Game Boy Color versions only!
In the NES and Master System versions (these screenshots are from the Master System port), all these enemies appear in the sixth island of the game as standard, essentially a replacement for Magical Island.

In the Game Boy Color version, Kiki Kaikai Island is unlocked by collecting all the Big Diamonds from Islands 1 to 7, and appears alongside the Secret Islands from the arcade game.

Insert a coin (only one!) then on the Player 1 side, press Up, Up, Up, Down, Right, Down, Left, Down, Down, Down, move over to Player 2's cnotrols and press Shot, Shot, Shot, then press Player 2 start. After beating the first Offensive and Defensive Halves, your satellite will be replaced by Flicky. [Source]
Flicky only appears in Offensive Halves- you'll take control of the satellite again in Defensive Halves.
Unlike the normal satellite, Flicky will skid around if you change direction sharply, so she makes the game much tougher!
This cheat also works in the PS2 port as part of Sega Ages 2500 Vol. 21 - SDI & Quartet, just make sure you don't have the game set on Free Play. [Source]



Plump Pop
(Arcade, 1987, Taito)

Syvalion
(Arcade, 1988, Taito)


XYZOLOG
from XYZOLOG - MSX, 1984, Taito / Compile

How to Encounter / Notes:
XYZOLOG can appear as a random boss in any chapter.
While it's probably a little bit of a stretch, given its name and appearance faintly resembling the x-shaped enemies in XYZOLOG, it's fair to assume Taito meant this as a little nod to this weird MSX game, developed for Taito by Compile. [Source] [Source]



Power Drift
(Arcade, 1988, Sega AM2)


F-14 Tomcat & Motorcycle
from After Burner II (F-14 Tomcat) - Arcade, 1987, Sega AM2

... This one really is stretching it, but c'mon, the disembodied head of Roy Adams! For some reason!?



On the Ball
(SNES, 1992, Taito)


Bubblen
from Bubble Bobble - Arcade, 1986, Taito

How to Unlock / Notes:
American / European versions only!
All three versions have a Ball Select screen accessed with a password- TYPE in the Japanese version, GFXJF in the American / European versions.
All of them have Crab, Chack'n, Dog and a spaceman also in the arcade version, but while the Japanese version has Roy Adams from the arcade game, the American and European versions replace him with Bubblen. [Source]
Bubblen's inclusion is pretty half-assed though- he has new shading, but he never spins around!



Champion Wrestler
(Arcade, 1989, Taito)


Rastan
from Rastan / Rastan Saga - Arcade, 1987, Taito

How to Unlock / Notes:
Rastan, appearing in this game under the name Miracle Rastan, is available from the start.

All of them return for a boss rush in the final round.

If done correctly, 'The Man' and Diabloon will be selected for you. [Source]
Diabloon's weapon system is based on the one from Turbo Force, so you'll lose power over time!
'The Man' is shrouded in shadows during your playthrough, until you reach the end and it's revealed to be Captain Waffle. Additionally, his ending mentions the 'Hildride' base as being destroyed, a new translation of the 'Hildroid', the main enemy forces from Spinal Breakers.

Karnov's Revenge
Fighter's History Dynamite

(Arcade/SNES, 1994, Data East)


Ox
from Karate Champ / Karate Dō - Arcade, 1984, Technōs Japan / Data East

How to Unlock / Notes:
Finish the game without losing a single round to fight Ox in a single-round battle after your character's ending.
Ox is not playable in any version of the game without the use of cheat devices.
Karate Champ technically isn't a Data East game- it was devloped by Technōs Japan and simply distributed by Data East. However, the rights to Karate Champ seem to be owned wholesale by Data East until their assets were sold off to G-mode, and so Ox is almost certainly intended to be a nod to the 'Get the Bull' bonus stage in Karate Champ.

(SNES, 1995, Data East)


Chelnov
from Atomic Runner Chelnov - Nuclear Man, the Fighter - Arcade, 1988, Data East

The King of Fighters Series
(Various, 1994-2013, SNK)



The King of Fighters is what you'd call an exceptional case. It's not explicitly a crossover game, but so many characters from previous SNK games appear that documenting all of them in the style of this page- i.e. providing screenshots of every single character- would be too intense. So, we've created a table with all the characters who appear in previous SNK games and are playable, not just Strikers. We'll be doing this like so: giving the name of an instalment of the series, then listing which characters were introduced in that game and where they're from:

The King of Fighters Maximum Impact Regulation "A"
(Arcade / Playstation 2, 2008, SNK Playmore)

Advance to 1995-1996!
